Asgard was attacked by the alien warlord Terraxia, who possed an item known as Tablet of Life and Time, which allowed her to resurrect the dead as zombies under her control.
Finding almost no dead to raise, since the
Aesir cremated their dead, she raised the body of the
Light Elf warrior Harokin, making him the first of her warriors. Together, they attacked an Asgardian village, killing the inhabitants and raising their bodies.
She was eventually defeated, and the Tablet of Life and Time was placed in
Odin's Vault to prevent its misuse. Harokin was returned to his grave.
